An experimental <particle physicist> who coauthored the <Christenson-Cronin-Fitch-Turlay kaon CP violation experiment>. Its <spark chambers> and magnetic analysis reconstructed two charged decay tracks in a neutral <kaon> beam. The rare two-<pion> signal exposed a failure of <CP symmetry>, showing why identifying a small decay component can test a fundamental symmetry.<Evidence for the 2π Decay of the K₂⁰ Meson by James H. Christenson and others>[pp. 138–140: apparatus, event selection and two-pion result]{ref}
